Description:
Title III of the Clean Air Act Amendments of 1990 established several study and regulatory requirements for toxic air pollutants that make dispersion and deposition modeling and the associated toxic emission inventories necessary. here are currently no comprehensive regional emission inventories compiled with the purpose of regional dispersion modeling of toxic emissions. imited emission inventories have or are being compiled although not necessarily for the purpose of modeling. here are useful databases from which information can be extracted to construct interim regional toxic emission inventories. n the long-term, basic information on toxics and improved inventory methodologies area needed to create inventories sufficient to drive sophisticated models. hese needs may be summarized as (1) improved toxic speciation and emission factors and application techniques, (2) improved knowledge of the atmospheric chemistry of toxic emissions and (3) governmental coordination in compiling emission inventories and in conducting research on toxic chemicals.
